Just setup a new PC with Proxmox and I'm having issues with the onboard motherboard NIC losing connectivity after a period of time. It can lose connection after 4 hours or the following day so it's not consistant. Once it loses connection I can no longer ping the IP address both to and from the onboard NIC. All VMs and the webgui aren't accessible either from the onboard NIC, The only way I can get it working again is to do a full reboot of the host.
My host specs are:
Asus B650E motherboard
Ryzen 7900
Intel 2.5Gb onboard NIC
Mellanox 10Gb SFP NIC
Troubleshooting steps I've done:
Tried 2 seperate new ethernet cables
Tried 2 seperate switches
Updated BIOS on motheboard
Tried booting PC into Windows for a few hours but haven't left it run overnight
Tried ifup/down commands
Tried recreating the vmbridge
Tried 2 different IP address
Intel onboard LED lights are active when ethernet cable is plugged in
I can still access the webgui using the Mellanox NIC
When the onboard NIC loses connection the ip addr command shows the NIC and vmbridge as UP however if I use ifdown then ifup on the interface then it show as DOWN and won't come back up but the physcal LEDs on the NIC still light up.
eno1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq master vmbr2 state DOWN group default qlen 1000

Can someone please help? What else can I try?
